It seems like
version_compare($version, '5.1', '<=') can also be of type integer . However, the property $_oldMysql is declared as type boolean . Maybe add an additional type check?
Our type inference engine has found a suspicous assignment of a value to a property. This check raises an issue when a value that can be of a mixed type is assigned to a property that is type hinted more strictly. For example, imagine you have a variable Either this assignment is in error or a type check should be added for that assignment. class Id
{
public $id;
public function __construct($id)
{
$this->id = $id;
}
}
class Account
{
/** @var Id $id */
public $id;
}
$account_id = false;
if (starsAreRight()) {
$account_id = new Id(42);
}
$account = new Account();
if ($account instanceof Id)
{
$account->id = $account_id;
}
